    Description / Table of Contents: Organometalphosphine Substituted Transition Metal Complexes, XII. Organometalphosphinepentacarbonylchromium(O), -molybdenum(O), and -tungsten(O) ComplexesThe reaction of hexacarbonylchromium with 1. tri(tert-butyl)phosphine, tris(trimethylsilyl)-, tris(trimethylgermyl)-, and tris(trimethylstannyl)phosphine as well as 2. with (trimethylsilyl)-diphenylphosphine, bis(trimethylsilyl)phenylphosphine, and bis(trimethylstannyl)phenyl-phosphine results in the elimination of one CO ligand and the formation of the corresponding organometalphosphinepentacarbonylchromium(O) complexes. In analogy to 1. hexacarbonyl molybdenum and hexacarbonyltungsten react with tri(tert-butyl)phosphine, tris(trimethylgermyl)phosphine, and tris(trimethylstannyl)phosphine to form the corresponding complexes. The i.r., u.v., 1H n.m.r., and 31P n.m.r. spectra are reported and discussed.
    Notes: Hexacarbonylchrom reagiert 1. mit Tri(tert.-butyl)-phosphin, Tris(trimethylsilyl)-, Tris(trimethylgermyl)- und Tris(trimethylstannyl)-phosphin sowie 2. mit Trimethylsilyl-diphenylphosphin, Bis(trimethylsilyl)-phenyl-phosphin und Bis(trimethylstannyl)-phenyl-phosphin unter Abspaltung eines CO-Liganden und Bildung entsprechender Organometallphosphin-pentacarbonyl-chrom(O)-Komplexe. Analog zu 1. reagieren Hexacarbonylmolybdän und Hexacarbonylwolfram mit Tri(tert.-butyl)-phosphin, Tris(trimethylgermyl)- und Tris(trimethylstannyl)-phosphin unter Bildung entsprechender Komplexe. Die Infrarot-, UV-, 1H-NMR- und 31P-NMR-Spektren werden mitgeteilt und diskutiert.
